Continuity mistake: Though he's leaped into someone else, we always see Sam as Sam, dressed in all the host's clothes (including glasses or sunglasses). His host is revealed only in reflections. But here, when he looks at his host-self in the mirror, the hat and clothes are all identical - except that the reflection is wearing glasses, and Sam isn't. (00:43:00)
Continuity mistake: When Al is standing next to the juke box, Sam walks over to make a selection, and when Al starts talking his reflection is visible on the glass. Later in this episode, Sam is talking to Al at the sink of the dressing room at the ball park. As Sam looks into the mirror he says he thinks Al is a vampire, to which Al replies, "Neurological holograms don't reflect, Sam." (00:26:00 - 01:15:30)
Continuity mistake: As Sam is preparing to go on stage as Don Quixote, after catching the lead actor, a quick cut to Dulcinea dancing is shown. It is supposed to be Sam's love interest and ex piano teacher Nicole as Dulcinea. However, you can see Nicole standing in the background, in the pink outfit she was wearing in scenes from the beginning of the episode. (00:41:55)
Continuity mistake: After throwing the laundry bags out the back of the truck, close up shots on Sam and the girl show the back of the truck being relatively empty. However, the next shot from the rear of the truck has the back full of laundry bags again.
Continuity mistake: When Sam and Ruben are fighting in the locker room they knock over a set of lockers (and only one set) and the door flies open on it. When they roll over the set of lockers the camera cuts and 2 sets of lockers are suddenly knocked down with all locker doors closed.
Continuity mistake: In the fight between Sam and Ruben in the locker room, Ruben has a white visor in his hands during the fight which magically disappears during the fight after a camera cut, and Ruben leaves after the coach breaks up the fight, without the visor.
Continuity mistake: When Sam tells Al the bartender that he knows another Al who uses the term "caca," Al leans over toward him to say, "Common expression." The camera angle reverses, and Al is abruptly not leaning any more, but standing back from the bar in his earlier position. (00:16:25)
Continuity mistake: In the party after the 1st game when Chewie and Sam are talking about the championship, Chewie pulls up a chair and sits on it backwards with his hands in his lap. After the cut to another camera, his arms are up on the back of the chair.
Continuity mistake: Willis drops his cap on the road when he runs away. It's still there in the long shot of him running, but after the commercial break we return to the same scene, and as Sam stands up, the cap is no longer on the road behind him. (00:35:10)
Continuity mistake: After Miss Melanie's son leaves, Sam/Jessie reaches out to steady her. His left hand is on her shoulder until the camera angle changes, when both his hands are at his sides. Change angles again, and his hand is back on her shoulder.
Continuity mistake: In one play during the montage sequence of the championship game, the quarterback for the Jaguars (Sam) is number 15 - but he wears 12 throughout the rest of the show. This is Sam, because Al later tells him to quit, so he's been playing the whole game.
Continuity mistake: When Sam is talking to Al in the store (while looking at car seats), Al checks on Margaret Dalton and holds the handset at chest level. The shot switches to Sam down on his knees and it's at his face level (about Al's waist). Then the shot switches back to Al and the handset is again chest high.
